Turkish deputy prime minister said rescue workers have pulled out 20 survivors from the rubble of three buildings collapsed by an earthquake in eastern Turkey.

Besir Atalay said at least five were killed and dozens of others trapped.

He said the November 9 quake toppled 25 buildings in the city of Van but only three were occupied since the others have been evacuated after suffering damages in last month's powerful quake.

The U.S. Geological Survey said that the 5.7-magnitude earthquake struck 16 kilometers south of the city of Van.

A 7.6-magnitude tremor hit just northeast of Van on October 23, killing about 600 people.

There have been hundreds of aftershocks since and thousands of people are still camping out in tents in freezing conditions.
